Application filed November 2. 1920. Serial No. 421,308.
To all whom. it may concern:
Be it known that I, VILLIAM M. HAMPTON. a citizen of the United States, residing at Whitewater, in the county of Cape Girardeau and State of Missouri, have invented vdrive by means of which the tractor can be guided and otherwise properly manipulated from theseat of the machine coupled to the tractor.
The invention embodies the novel construction of means for guiding the tractor from a remote point, and means for adjusting the clutch, shifting the gears and controlling the throttle.
The nature and advantages of the invention will be readily understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.
In the drawings forming parts of this application like numerals of reference indicate similiar parts in the several views and wherein:-
Figure 1- is a side elevation of a tractor showing the extension drive associated therewith.
Figure 2 is a top plan view.
Figure 3- is an enlarged fragmentary view of the extension drive separated from the tractor.

Figure 11-- 1s a sectional view, showing the bearing in which the shaft is mounted for actuating the gear shift lever.
Figure 12- is a sectional view taken at right angles to Figure 11.
Figure 13 is a view showing the connection between the extension drive and the clutch pedal.
Figure 1-l is a sectional view taken on line 14l-l of Figure 8.
Referring to the drawings in detail A indicates generally a tractor of well known construction. and B the machine coupled to the tractor.
The mechanism forming the subject matter of my invention embodies a frame including a vertically disposed bifurcated member 10 which reposes upon the differential housing of the tractor and is bolted or otherwise suitably secured thereto" as shown. Projecting forwardly from the member 10 are spaced parallel bars 11 which are connected together at one end by a transverse element 12. and also connected together at a point in their length by a transverse strip 13. Depending from the transverse element 12 is an apron 14 which is secured to the steering column 15 of the tractor through the instrumcntali'ty of U- shaped fastening elements 16. Secured to the machine B is a vertically disposed strip of suitable material indicated at '17 which together with the frame. above described constitutes the supporting structure vfor the movable parts of the mechanism for controlling the tractor. Secured to the strip 17 is a yoke 18 in which is pivotally mounted a panel 19.
lVhen equipping a tractor with the mechanism forming a subject matter of this invention. the steering wheel is removed. and a bevel gear 20 is associated with the steer ing post in place of the steering wheel. For guiding the tractor from a remote point. I utilize a shaft 21 which is journaled between the bifurcated member 10 and the transverse strip 13 of the frame above referred to. One end of the shaft supports a bevel gear 22 which meshes with the gear 20 to rotate the steering post upon rotation of the shaft 21. This shaft projects through the bifurcated member 10 and is formed with a yoke 23 forming part of universal joint. the yoke 24 carried by a square shaft 25 being connected with the yoke 23 in the usual manner to provide the universal coupling referred to. The square shaft 25 may be of any suitable length. and is telescopically fitted into the hollow square portion 26 of a section of the shaft 25. which section also includes a cylindrical portion 27 journaled in the panel 19. The cylindrical portion 27 is constructed to accommodate the steering wheel 28 of the tractor. which as above stated has been removed from the steering post of the tractor. liy reason of this construction and arrangement of parts. it is obvious that the tractor can be guided from the drivers seat of the machine B to 1 which the tractor 18 coupled. The universal joint provides for the proper steering. of the tractor irrespective of the angle at which it may be positioned with respect to the machine B. The swinging of panel 19 compensates for the relative movements of the tractor A and the machinev B whentravelling over irregular surface. to prevent breaking of the shaft 25 or subjecting the latter to undue strain.
In order to control the clutch of the tractor from the machine B, I make use of a. shaft 29 journaled in bearings 2-30 on the franze above mentioned. This shaft projects a. slight distance rearwardly of the bifurcated member 10 of the frame and is associated with the section 31 of a sectional shaft by means of a universal joint The section 31 is square and is telescopically fitted in the other section 33 of similar cross sectional configuration. the section 33 being journaled in the swinging panel 19. Projecting at right angles from the section 33 of this shaft is an extention 3i connected to a foot pedal 35 mounted upon the strip 17, by means of a rod 36. Projectinghorizontally from the shaft E25) is an arm 37 which has an offset extremity 38. and pivotally connected with this offset extremity is a dei'iending rod 39. The lower end of the rod carries a clamp -10 which connects the. rod 39 with the clutch pedal ll of the tractor. It is thus apparent that when the foot pedal 35 is depressei'l. the shaft 29 is rotated in the proper direction to depress the clutch pedal 451 and thus disengage the clutch. which is essential prior to shifting the guns for a change of speed.
Slidably and rotatably mounted upon the frame above mentioned is a shaft 42 ar ranged in bearings 43 one of which is equipped with rollers to minimize friction and thus facilitate sliding of the shaft for the purpose to be presently described. This shaft is coupled to the section 45 of a sectional shaft by a. universal joint -16. the sec tion 45 being square and telescopically titted in the other section 47 of the shaft which includes a hollow portion of the same cross section configuration as the section -15. and a cylindrical portion 48 which is both slidablv and rotatably fitted to the swinging panel 19. Dependingfrom the shaft 42 is an arm l9 which terminates in a plane occupied by the upper end of the gear shaft lever 50. the latter being provided with an opening to receive a horizontally disposed stub shaft 51 which is pivoted to the lower end of the arm t9; It will thus be noted, that when the shaft 12 is rotated the shaft lever 50 is moved to ono side or the other in the usualmanner t0. g ar the tractor for different speeds. the lever 50 being subse quently moved in either forward or rearward direction. It will be observed that the operating shafts associated with the swinging panel 19 all include telescopic sections so that the length of the shafts may be varied as occasion requires, and to permit useof the mechanism in the tractor with the machines of different characters. However. in order to effecta sliding adjustment of the shaft 42 for the purpose above mentioned. it is necessary that the sections 45 and 47 of the operating shaft be held fixed relatively in an adjusted position. and for this purpose I provide the section with teeth 52. the latter being engaged by a pivoted locking! dog mounted on the section L7 of said shaft. This dog is spring-pressed and normally held out of engagementfrom the section 45 of the shaft. Pivoted upon the handle 54 of this shaft is a manipulating element which is adapted to be actuated by the handle 54, is grasped to throw the dog 53 into engagement with the teeth 52, the dog 53 being connected with the manipulating element by means of a rod 56.
Journaled in the bifurcated member 10 is a. shaft 5T'which is suitably connected to the throttle 58 as at 59. The shaft 57 is connected by means of a universal joint 60 to the section 61 of a sectional operating shaft for imparting rotation to the shaft 57. The other section 62 of said sectional shaft hollow to telescopically receive the section (it. The section 62 passes through a swingin; panel 19 and is equipped with a lever (33 by means of which sectional shaft is actuatcd. Except when the sections 45 and 17 of the shaft which actuates the gear shaft control lever is fixed relatively, the sections of each sectional shaft are permitted movement toward and away from each other when the tractor and the machine B coupled thereto travel over rough or irregular surface.
While it is believed that from the foregoing description the nature and advantages of the invention will be readily understood, I desire to have it known that I do not limit myself to what is shown and described and that such changes may be resorted to when desired as fall in the scope of what is claimed.
What I claim 1. An extei'ision drive for tractors comprising a s in ing structure, a plurality of shafts oin led on said structure and connected respectively to the clutch lledal,
